@RioLongacre @aripap I took a terrible photo, but it’s Jeff and Ari.

@JudSpencer I remember doing interviews to research what the definition of SPO in 2021 - oh boy was that a mess.

[Dennis T Cheung @dtc]

I got my copy of Yield signed by @aripap at @marketecturetv Live!

Great event!

[Ari Paparo @aripap]

Getting ready to go on with @JeremyBloomHere

2/2 and @CaliforniaDCA. Bought new at Costco (Mar 2020, $2,099+tax). Failure began Oct 2025. 4 repair visits. LG spec sheet states “Sealed System 7 Years” here: https://t.co/gWYrqUrAFo

[Dennis T Cheung @dtc]

1/2 @LGUSSupport 5-month saga: my LG LMXS28626S has a sealed-system leak and your authorized tech says it’s unrepairable. Your team claims sealed-system warranty is 5 years, but LG’s own doc says 7 years. Honor it with full refund or I will file complaints with @AGRobBonta

In case you missed it, here are the details on Commitments Hub that we launched last fall:

If you're an advertiser managing spending agreements with publishers, I'd love to connect.

Happy New Year! 🥂

Starting Year 5 at Amazon Ads. Proud of what my teams have shipped to help customers: creative tools for Fire TV self-service performance advertisers, PG deals and O&O deals-based buying in Amazon DSP, and Commitments Hub.

Excited for what’s next in 2026!

@aripap Do you have TIDs on the slides or something?

[Dennis T Cheung @dtc]

@jslee @101Programmatic Interesting - how would this work?

Would one setting be "I absolutely need to spend $10M in 2025 with Pub Y - prioritize all my spend to make that happen", while another setting would be "Please do your best to spend $10M in 2025 with Pub Y?"

What would the trade off be?

[Dennis T Cheung @dtc]

@patio11 @pitdesi @SwiftOnSecurity Wait this thread started off about the ease and cost of getting lens prescriptions (licensing).

But that seems separate from the cost of getting *frames*

[Dennis T Cheung @dtc]

@JudSpencer A joke that didn't land at all.

[Dennis T Cheung @dtc]

I led the team that launched PG buying at Amazon DSP - and it sounds like our fee is pretty popular!

There's much more to come from Amazon DSP, so stay tuned...

[Bill Wise @billwise]

@aripap Amazon PG deals are 1.0%, no hidden data fees AND 0% on their O&O. Independent DSPs simply cannot compete on pricing.

[Dennis T Cheung @dtc]

@MichaelSFBA Uh oh did she forget to tag off and get charged from St Pancras to Gilroy?

[Dennis T Cheung @dtc]

@accidentalflyer @regulatorynerd Maybe it’s part of the Rivian collab effort.

[Dennis T Cheung @dtc]

@accidentalflyer Maybe they needed to pick up some pizza back to their innovation center?

[Dennis T Cheung @dtc]

@sp6runderrated Broadly I agree.

I'd also note that TNG was on broadcast so there was a larger potential initial audience. And TNG on the whole is a positive show. Unlike The Shield which... uh... wasn't. If the rights ever get resolved, I'd recommend watching Homicide: Life on the streets

[Dennis T Cheung @dtc]

@sp6runderrated The Shield is the only show that I bought the Blu-ray set for because I figured it would disappear unlike other shows (ST:TNG) that will live on in some form forever. And yes I’ve never rewatched it.

[Dennis T Cheung @dtc]

@SarahSluis My mind was blown when I saw this article last year https://t.co/rFyWup6qDO

This whole situation has vibes you mention, but on super steroids (pun intended)

[Dennis T Cheung @dtc]

@constans Google Street view shows there were sidewalk vendors a decade ago at 86th and Broadway!
And that account says they're 5th gen Manhattan? This person would probably have died if they went down to Chinatown or Hells Kitchen in the 1980s like I regularly did.
